How Dark Is 50 Window Tint?

If you are wondering how dark is 50 window tint, you have come to the right place. In this article, we will cover several aspects of this product, including Visible light transmission, Legality, and Effects on visual acuity and depth perception. Depending on your preferences, you may want to opt for a darker tint than 20. However, this type of tint may make it difficult to see through. For safety reasons, you should always opt for a dark tint if you have a car.

How Dark Is 50 Window Tint?

Visible light transmitt

The amount of light that can pass through the window film is known as the visible light transmittance (VLT) of the film. If the VLT is fifty, then half of the sun’s rays will not pass through the window. On the other hand, if the VLT is eighty percent, then seventy-five percent of the visible light will be transmitted. This means that the tinted windows will reduce the solar heat gain of the vehicle by as much as 60 percent.

When choosing a window film, you should look for a window film with the highest VLT possible. This will be the best value for the desired amount of protection. The higher the VLT, the more visible light will be allowed through the film. For instance, a film with a VLT of fifty percent will allow 80% of light to pass through, while one with a VLT of five percent will let only 5% of visible light through.


A good place to start researching the legality of 50 window tint is the state laws governing vehicle tinting. Some states allow tinting up to a certain percent of windows and restrict the amount of light entering the car. While this can make driving a challenge, the added protection provided by window tinting also helps prevent the police from seeing inside the car. To avoid legal problems, be sure to contact the state DMV and have the tint inspected.

Before installing window tint, always consult your state’s laws regarding its legality. Certain colors and reflective finishes are prohibited by state law, while others do not have any restrictions at all. The AS-1 line, which is found on most motor vehicle windshields, will tell you whether or not 50 percent of window tint is legal in your state. In most cases, tinting is legal as long as it does not obstruct glare or visibility or causes discomfort.

Effects On Visual Acuity

Using Landolt’s circle charts, researchers measured each subject’s visual acuity under various conditions of daytime illumination and nighttime darkness. The results of this study indicate that tinted windshields do not alter visual acuity in the short term. In fact, the study showed that increased illumination enhances visual acuity, despite no effect of windshield tint on driving.

The fovea is the part of the retina that is responsible for achieving sharpest visual acuity. It corresponds to the center of the visual field and is constantly used to fixate on objects. Because the fovea is completely composed of cones and has no rods, it’s sensitive to low luminance levels. It’s because of this that low-luminance environments can create a blind spot, 5-10 degrees in diameter. In this area, objects viewed directly may disappear or appear blurry.

A study found that age, gender, and glare were significant effects on the resulting visual acuity. Older subjects did worse in the visual acuity test than younger ones. However, increased glare levels resulted in a higher contrast threshold. Thus, tinted windows improve eye health and reduce eye strain. This study is the first to show a link between tinted windows and visual acuity.

Effects on depth perception

Darker windows provide more protection from ultraviolet rays, but beyond 30% they are illegal and potentially dangerous. Additionally, a very dark window film reduces visibility at night. Stationary objects may blend into the background if the film is too dark. This may make it difficult for drivers to distinguish objects in dark settings. Also, people wearing dark clothing may have difficulty seeing. The effects of 50 percent window tint may be less severe in older people.


This study compares two types of windshields. Both perform similarly when it comes to glare response and visual acuity. The implications of these results, limitations, and future plans are discussed. However, this study is not without limitations. Further research is necessary to assess the effect of window tints on the perception of depth. This paper is only one of a series of studies on the subject. Please refer to the related references below for more information on these studies.
